It would be nice to tell while viewing a recipe if i have enough total ingredients to work without going to the brew store. Maybe toggling an icon that gives a thumbs up/down or green/red next to ingredients to signal if they're present. Showing all ingredients in the deduction page when clicking 'brew' would also be nice. Then perhaps a view that shows just missing ingredients so I can print a shopping list (only yeast, or yeast and 1oz of this/that). When i click brew I do have the option to deduct from inventory. It will list ingredients that I have, how much will be used and the new resulting qty. However; any ingredients that I do not have are not listed. So i have to figure out what's missing and write it down for a quick trip to the store.
